This interface encapsulates the necessary methods for representing aFuzzy Location, one that does not have clear start and/or end points.This will initially serve to handle features from Genbank/EMBL featuretables that are written as 1^100 meaning between bases 1 and 100 or<100..300 meaning it starts somewhere before 100. Advancedimplementations of this interface may be able to handle the necessarylogic of overlaps/intersection/contains/union. It was constructed tohandle fuzzy locations that can be represented in Genbank/EMBL.

User feedback is an integral part of the evolution of this and otherBioperl modules. Send your comments and suggestions preferably to oneof the Bioperl mailing lists. Your participation is much appreciated.

Please direct usage questions or support issues to the mailing list:bioperl-l@bioperl.orgrather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

Title : coordinate_policy Usage : $policy = $location->coordinate_policy(); $location->coordinate_policy($mypolicy); # set may not be possible Function: Get the coordinate computing policy employed by this object.
See Bio::Location::CoordinatePolicyI for documentation about
the policy object and its use.
The interface *does not* require implementing classes to accept
setting of a different policy. The implementation provided here
does, however, allow to do so.
Implementors of this interface are expected to initialize every
new instance with a CoordinatePolicyI object. The implementation
provided here will return a default policy object if none has
been set yet. To change this default policy object call this
method as a class method with an appropriate argument. Note that
in this case only subsequently created Location objects will be
affected.
Returns : A Bio::Location::CoordinatePolicyI implementing object.
Args : On set, a Bio::Location::CoordinatePolicyI implementing object.
